Find the value of k to the given equation
if one root is double the other.
Solution:
Consider the given equation
If a = 2, b = k, and c = 25, then substitute these values to the Sum of the Roots Formula
From the word problem, if r1 = 2r2, then
From the Product of the Roots Formula
Substitute the value of the variables to the above equation
Therefore, the answer is k = 15.
